  1. 1. Syngas production by integrating thermal conversion processes in an existing biorefinery

    Detta är en avhandling från Umeå : Umeå Universitet

    Författare :Katarina Åberg; Umeå universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; biofuels; syngas; gasification; torrefaction; methane reforming; H2 CO ratio; system analysis; CO2 negativity;

    Sammanfattning : The use of carbon from fossil-based resources result in changes in the earth’s climate due to emissions of greenhouse gases. Biomass is the only renewable source of carbon that may be converted to transportation fuels and chemicals, markets now fully dominated by traditional oil supply. LÄS MER

  2. 2. Catalytic conversion of syngas to higher alcohols over MoS2-based catalysts

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Robert Andersson; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conversion; higher alcohols; mixed alcohols; MoS2; syngas; Chemical Engineering; Kemiteknik;

    Sammanfattning : The present thesis concerns catalytic conversion of syngas (H2+ CO) into a blend of methanol and higher alcohols, an attractive way of producing fuels and chemicals. This route has the potential to reduce the oil dependence in the transport sector and, with the use of biomass for the syngas generation, produce CO2-neutral fuels. LÄS MER

  3. 3. Assessing the Integration of Biomass Gasification-Based Production of Chemicals — Case Study of an Oxo Synthesis Plant

    Detta är en avhandling från Chalmers University of Technology

    Författare :Maria Arvidsson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; biorefinery; gasification; syngas; chemicals production; oxo synthesis;

    Sammanfattning : The chemical industry sector is energy-intensive and highly dependent on fossil feedstock. The primary long-term option to reduce fossil feedstock dependence and greenhouse gas (GHG) emissions is to switch to renewable feedstock. LÄS MER

  4. 4. Fischer-Tropsch Synthesis over Cobalt-based Catalysts for BTL applications

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Matteo Lualdi; KTH.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cobalt; Fischer-Tropsch; syngas; selectivity;

    Sammanfattning : Fischer-Tropsch synthesis is a commercial technology that allows converting synthesis gas, a mixture of CO and H2, into fuels and chemicals. This process could be one of the actors in the reduction of oil dependency of the transportation sector. LÄS MER

  5. 5. Application of Laser-based Diagnostics to a Prototype Gas Turbine Burner at Selected Pressures

    Detta är en avhandling från Lund University (Media-Tryck)

    Författare :Ronald Whiddon; Lunds universitet.; Lund University.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; OH; Laser Diagnostics; Elevated Pressure; Syngas; DLE; NOx; Combustion; Gas Turbine; PIV; PLIF; Pilot; SGT-750; Fysicumarkivet A:2014:Whiddon;

    Sammanfattning : Popular Abstract in English There is a natural tendency to take advantage of the most convenient energy source available. In this usage, convenient may mean most abundant, easiest to harvest or simplest to handle. Convenient will also correspond to cheapest in many instances. LÄS MER
